Why the independent testing market grew a chemistry arm and not a microbiology one
The absence of microbiological capability in this market is a commercial fact with a straightforward explanation, and it is worth understanding before blaming anybody for it.
LAL, kinetic chromogenic, recombinant factor C: three ways to the same figure
Three compendial method families are in routine use and a fourth, based on a recombinant enzyme rather than crab lysate, is now compendial in its own right.
What changed at MKM in September, and what the company will not say about it

Asparagine, glycine, and the two residues that decide a shelf life
We describe each pathway in enough chemical detail to explain why it is invisible to the method the trade uses, because that is the part which has practical consequences.

What VendorInvestigate is able to certify about a sealed vial, and what it is not
Every certificate circulating in this market answers a question about molecules. Almost none answers a question about organisms, pyrogens, or the integrity of the seal.
Six words a verification badge would need to mean anything
The Journal does not treat a badge as evidence and states so wherever it reports one.
Independent analysis puts a CPC orforglipron lot at 95.3%, against 92.5% on the certificate
The result is unremarkable. What the report omits is not.

Medutest result on a Suzhou semaglutide lot lands 4.3 points below the supplier’s figure
The result is unremarkable. What the report omits is not.
Why Medutest can tell you the mass is right and not that the sequence is
The Journal’s standing position: a mass that matches is necessary evidence of identity and nowhere near sufficient.
Medutest result on a Shanghai mazdutide lot lands 1.2 points below the supplier’s figure
The Journal submitted the sample and paid for the analysis. The vendor was told in advance.
Independent analysis puts a SSA dulaglutide lot at 96.0%, against 95.0% on the certificate
A reminder that a purity figure is the output of a method, and that methods differ.
